Kicking off a series that explores the relationship between human memory and photography in the age of smartphone cameras, Audie Cornish talks to psychologist Linda Henkel about whether photographs impair our memory.

“As soon as you hit click on that camera, it’s as if you’ve outsourced your memory,” Henkel says. “Anytime we kind of count on these external memory devices, we’re taking away from the kind of mental cognitive processing that might help us actually remember that stuff on our own.”
